So, my professor puts up these exam equations before the exam to give us a chance to scramble around like chickens with our heads cut off trying to figure it out. I'm in beginning Astronomy and my book doesn't teach how to solve this, we're left to our own devices to figure it out. I could use some help!
A newly discovered star has an apparent magnitude of -1.0, a luminosity of 1000 LSUN and a surface temperature of 5 TSUN. Calculate:
a) the radius of the star
b) the absolute magnitude of the star,
c) the distance of the star in parasecs.
